I have an umbrella policy of me if someone ever gets past my LLC if they trip on the sidewalk, but I was thinking if I have say 30 houses at $50/mo that's $1500/mo in savings, $18,000/yr in insurance savings alone.

Meters are inside the buildings, if the leak is past the sidewalk, usually it’s in the city then.

Are there sidewalks, parks, or other suitable walking areas nearby?

There is a sidewalk that meets the stone foundation.The brownish area in the center of the photo is a small problem area. 

We have had an inspection done, and there are a couple of things we'll probably need to take care of right away with the property: a flashing problem and a very uneven sidewalk problem that the current tenants have complained about to the previous owner many times.

.- Outside lights burnt out- Stoves that don't light but always light no problem when I'm there- Missing screens, that tenants have destroyed and then throw the frame away to hide it- Top pane on double hung window drops when unlocked- Insufficient heat in a room, that's a fun oneIn our parks;- Rise of more than 1" in sidewalk squares- Not having vehicle stops in front of gas meters- Vehicle set back from homes- Pedestals not secureThese are just some that come to mind but there is a laundry list more.

The cost of living is great, there is not trash on the streets and sidewalks, few homeless- even then, they are well kept by the volunteering community.

If this is under sidewalks and parking, it could cost a lot more than just the connection fee, since normally septic systems run to the back of the properties and City sewer runs to the front. 

And then this guy PUT THE DUMPSTER ON THE SIDEWALK.

I am a first time home buyer and I decided that building would be the best way to go....joke's on me.Background: In August of 2016 I paid cash for two improved lots (ie: has sidewalks, paved street, utilities stubbed out), each one a 1/4 of an acre for a total of $9,995.
